Eight glycosides of 2α, 19α-dihydroxyoleanolic acid derivatives, including trachelosperosides D-1, D-2, E-1, F-2, and arjungenin-23,28-bis-O- glucoside and -28-O-xylopyranosyl-(1-2)-glucopyranoside, were isolated from the whole plant of Trachelospermum asiacitum, along with the known glucosides arjunglucoside I and arjungenin-3,28-bis-O-glucoside, and their structures were determined.

, p. 907 - 910 (2007/10/02)
From the stem bark of Symplocos spicata a mixture of triterpenoid saponins was obtained.It behaved as a pure compound in TLC and HPLC, but heterogeneity was suspected on the basis of chemical and NMR spectral data.It was separated to give two analogous glycosides, which were identified as 3,28-O-bis-β-D-glucopyranosides of 19α-hydroxyarjunolic and 19α-hydroxyasiatic acids.Key Word Index - Symplocos spicata; Symplocaceae; separation of analogous glycosides; structure elucidation; triterpenoid saponins; 3,28-O-bisglucosides of 19α-hydroxyarjunolic and 19α-hydroxyasiatic acids.
